I know there are alot of threads on cover letters and resumes and landing the interview--I've read all of those. But, what advice would someone give to someone who is able to secure several interviews but not get a position. How would I know what to improve if all I get is the dreaded rejection letter. I have e-mailed Ps back for feedback but have never received a response. It's almost like I've proven that I'm not good enough for them to even respond back to. How do you avoid making the same mistake over and over again when you do not know what the mistake is.
